An official first action method for the extraction of light filth from spices, 44.A03--44.A05, was modified for the analyses of ground paprika. The sample is extracted with isopropanol and light filth is isolated from 40% isopropanol with mineral oil. Eight collaborators analyzed 4 paprika samples, 2 by the official method and 2 by the proposed method. Average recoveries of added elytral squares were 97 and 66%, respectively, for the proposed and official methods. Recoveries of added rodent hairs were 94 and 61%, respectively. The method has been adopted as official first action for the extraction of light filth from ground paprika.
一种从香料中提取轻质杂质的官方首次行动方法（44.A03 - 44.A05）被修改用于辣椒粉分析。样品用异丙醇提取，轻质杂质通过矿物油从40%的异丙醇中分离出来。八位合作者分析了4个辣椒粉样品，其中2个采用官方方法，2个采用提议的方法。对于提议方法和官方方法，添加的甲虫翅鞘方块的平均回收率分别为97%和66%。添加的鼠毛回收率分别为94%和61%。该方法已被采用为从辣椒粉中提取轻质杂质的官方首次行动方法。
